Hemp-BRAKE.

PECIFCATION forming part of Letters Patent Nol 465,433, dated December 15, 1891.

Application filed November 26, 1890. Serial No. 372.690. (No model.)

To all whom it may concern.:

Be it known that I, JOHN J. HAWKiNs, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hemp-Brakes, of which the following is a specication.

My invention relates to hemp-brakes which employ a rotary beater, a stationary breaker,

`and a feeding roll or rolls for breaking and My invention herein describedworks upon a different principle and is more `satisfactory in results.

f The various features of my invention will be fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 shows a sectional side elevation of my improvement. Fig. 2 is a side elevation of my improvement with the casing of the machine removed to show the driving mechanism. Fig. 3 is a modification of Fig. l.

l represents the ground-Wheels.

2 is the axle, which is journaled to the main frame 3.

4 represents the bed upon which the Working parts of said apparatus are mounted.

5 represents front feed-rolls.

6 represents a stationary breaking-bar that is supported transversely in front of a rotary beater and riddle above the path of the material fed thereto and in such position as to project inward and downward toward said beater and riddle.

7 represents one of the heads of the revolvingbeater, which is journaled upon the shaft 8.

B represents breaking-bars which are secured to the heads 7. Said beater is revolved by any suitable power.

l0 represents delivery-rolls, and 1l a breaking-bar at the rear end of the machine.

l2 represents a curb or housing.

13 represents an opening` th rough which the hemp is delivered onto the table 14..

A represents a feeding-table on the front end of the machine.

It will be seen that the arrangement of the rotary' heads 7 and attached breaking-bars .B is such as to form a revolving beater and riddle or cleaner for removing hurds from the hemp.

Fig. 3 is a modification of Fig. l, showing only one feed and one delivery roll. This will accomplish the Work indiiferently Well; but the form shown in Fig. l is the preferred form of construction.

Mode of operation: Hemp-stalks are laid upon the table A and fed in by the rollers 5. They are caught by the breaking-bars B and carried up against the stationary breakingbar 6. In practice I prefer to have the feedrolls 5 driven much slower in speed than the revolving beaters, so that the break-bars B will strike the hurds o an inch and one-half or so in length and break themin two. If the feedrolls are omitted or driven at too high speed, the hemp is pulled through too rapidly and it is not suiciently broken. By employing one or more feed-rolls 5 this objection is avoided. It is desirable to keep the stream or flow of broken fibers loose after they have been acted upon by the stationary bar 6 and to be whipped by the revolving breakers B, so as to allow the hurds to drop out as they pass over it. It iiexible blades or apronsor other-.devices are employed to hold the hemp down upon the beating-bars B, they prevent the hurds from dropping out; but if the said IOO performs the double function of breaking and cleaning. The hurds Which pass out the delivery-rolls are easily shaken off.

Having described my invention, what I claim is- 1. In a hemp-brake, the combination of a feeding-roll, a rotary beaterand riddle co1nposed of the heads 7 aud attached beater-bars B, and a stationary breaking-bar 6, rigidly supported in front of said rotary beater and riddle above the path of the material fed thereto and projecting' toward the beater and riddle, substantially as described. I

2. In a hemp-brake, the combination of a feeding-roll 5, a rotary beater and riddle composed of the heads 7 and attached beater-bars B, and the stationary breaking'bar 6, supported transversely in front ot' said rotary beater and riddle above the path of the mazo terial fed thereto and projectingr inward and downward toward the beater and riddle, sub` stantially as described.

3. In a hemp-brake, the combination of the stationary breakin ,fr-bar 6, a rotary beater and riddle composed of the heads 7.and beaterbars B, and a delivery-roll l0, substantially JOHN J. HAWKINS. l
